###### Vocabulary:

Multi-step, Addition, Subtraction, Equation, Equal, Unknown Numbers

Activities:

Students continued to solve multi-step problems. Students solved

problems from left to right, then solved for the unknown number. First, students used counters to add or subtract a given amount. Then, students used hundreds charts to add and subtract. This allowed students to add or take away quantities with more ease.

Ex. ? + 17 + 14 -11 = 37

Step 1: 17 + 14 = 31

Step 2: 31 - 11 = 20

Step 3: ? + 20 = 37

Step 4: 37 - 20 = ?

The unknown number is 17.

Students identified the object that did not belong. Then students told why the object did not belong. Next, students told what the group of objects had in common. Different properties we identified are color, shape, and size.
